Hello! Thanks for your comment. I always use a my stand mixer, but I don’t mention it because people might think that it’s not possible to do the recipe without it. To answer your question, it won’t over mix because it’s gluten free. The thing that make it hard is that the gluten is over activated. When I bake muffins with gluten, I only mix at a low speed and it’s only until ingredients are blended. I hope it answers your question. Have a nice day!
